editor-stream-out-base% : class?

  superclass: object%

An editor-stream-out-base% object is used by an editor-stream-out% object to perform low-level writing of data.

The editor-stream-out-base% class is never instantiated directly, but the derived class editor-stream-out-bytes-base% can be instantiated. New derived classes must override all of the methods described in this section.

method

(send an-editor-stream-out-base bad?) → boolean?

Returns #t if there has been an error writing to the stream, #f otherwise.

method

(send an-editor-stream-out-base seek pos) → void?

  pos : exact-nonnegative-integer?
Moves to the specified absolute position in the stream.

method

(send an-editor-stream-out-base tell)

 → exact-nonnegative-integer?
Returns the current stream position.

method

(send an-editor-stream-out-base write data) → void?

  data : (listof char?)
Writes data (encoded as Latin-1 characters) to the stream. This method is implemented by default via write-bytes.

method

(send an-editor-stream-out-base write-bytes bstr) → void?

  bstr : bytes?
Writes data to the stream.
